Going to WA? The best way to move around the Perth metro area is the SmartRider card (similar to Opal in Sydney). A new card costs 10$ and has no credit on it. I won't use my card anymore and am happy to give it away for free. You only pay the actual balance on the card, not the 10$ purchase price. The card has 23.12$ balance, you can have it for 23$. Pick up in Sydney CBD or Marrickville. If you want me to post it, 1$ extra for the AU Post stamp.
